Slice in halve your washed white peaches and remove the stones. Place in a blender and blitz for a few seconds until nice smooth. If you prefer not to use a blender you can also mash the peaches through a sieve, but make sure you push through the skin as well for their beautiful color.
Transfer the puree into a glass pitcher and then pour 3/4 of your Prosecco into the pitcher an stir gently.
Pour Bellini into 6 Champagne flutes or tall slim glasses and top of with the rest of the Prosecco. You can garnish with thinly sliced peaches
You can also make individual servings: just pour peach puree into the glass and slowly add the Prosecco. Stir gently and pour a little on the top and garnish
